Sending invoice only for some customers

Hi @edosantillana,

Although the code is working at my end, I just added a check to the code in order to display previous generated invoices, even if the customers didn’t include the VAT number:

/**
 * Enable invoice only if the customer fill the NIF/CIF field
 */
add_filter( 'wpo_wcpdf_document_is_allowed', 'wpo_wcpdf_allow_invoice_if_customer_has_vat_number', 10, 2 );
function wpo_wcpdf_allow_invoice_if_customer_has_vat_number( $allowed, $document ) {
	if ( $document->exists() ) {
		return $allowed;
	}
	if ( $document->type == 'invoice' ) {
		if ( $order = $document->order ) {
			$allowed = ( ! empty( $order->get_meta( 'billing_nif' ) ) ) ? true : false;
		}
	}
	return $allowed;
}

If you still don’t see the invoice button, even if your customer included the VAT number, you’ll need to double-check that your VAT number fields is indeed named billing_nif (sometimes it has an underscore at behind: _billing_nif). Also check if you’re disabling the invoice for certain order statuses, under WooCommerce > PDF Invoices > Documents > Invoice > Disable for setting.

Hope it works 🙂

Hi @edosantillana,

I notice that the invoice button appears only in the customers that included the VAT number at it suppose to be, but the check to the code that you mention should show all the invoices, even if the customer didn’t include the VAT number. As I said, it works fine now, at it suppose to be, but your argument makes me think.

The extra check that I added in my previous code is to allow our plugin to display the documents already created in the past, before you have added the VAT number field. Without that check, those documents will be hidden if the customer didn’t include the VAT number in the order. If you’re using the VAT number field from the beginning, this check it’s not necessary, although I recommend keeping it 😉

The invoice button appears with a red dot over it, it means that I have to click in the button in order to send the invoice to the customer? Because once click the button a green check appears, or the invoice is sent automatically once the order was completed? In the settings is selected that way, once Completed.

We use the that red dot to semantically relate our icons to PDF documents, but it doesn’t change. However, there are two types of icons: without and with a green check mark. When you see the green check mark means that the document already exists for that particular order.

When you click on the icon, when it doesn’t yet have the mark, the document will be created, but this doesn’t mean that the document will be sent to the customer. To do so, you need to check the WooCommerce email notification in which you want to attach the invoices, under WooCommerce > PDF Invoices > Documents > Invoice > Attach to:

Please note that the email will create the invoice in order to be able to attachment it to the message. Therefore, it’s recommendable to select only the status email notifications that are sent when the customer paid the order, by default Processing and Completing.

Hi @edosantillana,

I’m glad to know it works! 🙂

If you don’t mind and have the time, do you think you could leave us a review?

Thanks in advance and all the best with your store!
